SPINNING RING CLEANING MEANS Filed Jan. 28, 1959 SPINNING RING CLEANING MEANS Andrew J. Wayson, Needham, Mass., assignor to Merriman Bros, Inc., Boston, Mass, a corporation of Massachusetts Application January 28, 1959, Serial No. 789,676

6 Claims. (Cl. 57-56) This invention relates to the textile industry and is particularly concerned with means for cleaning accumulations of fud from the under side of spinning rings. The invention is applicable to all types of vertical rings.

In spinning rings of the self-lubricating vertical type which is illustrated herein, the holder therefor may consist of a circular support having on its interior upwardly and downwardly extending flanges which fit the confines of the corresponding circumferential exterior groove in the ring. Other smaller grooves are also present in the ring in which are positioned the oil conveying wicks.

In normal operation of spinning frames utilizing this type of ring as well as the earlier forms which are lubricated in a different and generally less satisfactory way, it has been found that after a period of use a quantity of material known in the trade as fud gradually collects on the exterior lower side of the ring and on the under side of the circular support. In this location it is completely out of sight and at the outset causes no trouble. In due time, however, the fud, which is a mixture of very short fibers which have broken loose during the spinning operation and lubricating oil, builds up on the under side of the support to a degree where it begins to interfere with operation of the traveler. That is, the lower upwardly turned end of the traveler begins to make contact with the increasing amount of fud and as a result traveler operation is impaired. When this condition has developed, it means that the spinning frame must be shut down while an operator goes from ring to ring with a compressed air nozzle which he sweeps around on the under side of the ring to blow the accumulated fud loose. When this cleaning treatment has been given to all of the rings on both sides of the spinning frame, the frame may then be put back in operation. To carry out this procedure requires a substantial period of time, and in many cases the cleaning is not completely accomplished because of the relative inaccessibility of the places in which the fud accumulates. This undesirable condition has been present in the industry for many years, and as far as I am aware no solution up to the present has been known in the trade.

Accordingly, the principal object of my invention is to provide a ring and ring holder construction which functions in the usual manner to support the spinning ring but at the same time makes it possible to clear the ring of accumulated fud in a quick and easy manner. This result is achieved by making the ring holder or the ring supporting flange with a substantial number of circularly arranged slots or holes which in the aggregate constitute a major proportion of the ring holder circumference. These openings are located in the holder or flange at positions directly above the location at which the fud normally accumulates.

The holes so formed in the ring holder or flange do not afl'ect the strength or holding capacity thereof, but they provide means whereby the operator may clear the ring of fud by directing an air blast downwardly through the holes as distinguished from the former practice which 2,935,555 Patented May 17, 1960 required getting under the ring to direct the air blast upwardly against an imperforate structure.

By the construction that will hereinafter be described, it becomes possible to clear the rings of fud in a fraction of the time formerly required, and since the operation is easily performed, the cleaning may be carried out at more frequent intervals, thus giving assurance that the travelers will at all times run freely.

An additional inherent advantage provided by the present construction is that the holes or apertures through the holder or support provide a substantially increased surface area from which heat generated in the ring may be dissipated. The cooling effect provided by this construction is augmented because of the proximity of the apertures to the spinning package which is constantly generating an outward flow of air. The moving air passes in part through the holes to aid the cooling process. Some of the holes are between the ring and the oil well. This results in appreciable cooling of the oil therein.

These and other advantages of the invention will become more apparent as the description proceeds with the aid of the accompanying drawings in which Fig. 1 is a plan View of a vertical type spinning ring supported by a holder made in accord with the invention.

Fig. 2 is a section taken on the line 22 of Fig. 1.

Fig. 3 is a section taken on the line 3--3 of Fig. 1.

Fig. 4 is a section taken on the line 44 of Fig. 1.

Fig. 5 is a view similar to Fig. 2 showing an accumulation of fud on the under side of the holder and on the lower exterior of the ring.

Fig. 6 shows the manner in which an air blast applied to the upper side of the holder will cause the fud to be fully dislodged, thereby clearing the ring.

Fig. 7 shows the invention applied to that type of spinning ring having an exterior flange which is supported by a holder intermediate the ring rail or directly on the ring rail.

Fig. 8 shows another form in which the flange of the ring is similar to that shown in Fig. 7, but the flange and holder overlap completely and the openings extend through both flange and holder.

Referring to Fig. 1, a ring holder is indicated at 2. This is designed and constructed to properly support a vertical spinning ring 4. The holder is split at 6 whereby it may be spread apart for insertion or removal of the ring 4. The holder also includes as an integral part thereof an oil reservoir 8 in which is periodically placed as needed a quantity of oil through a valve member 19.

As shown in Figs. 2, 3, 5 and 6, the ring 4 has a wide exterior circumferential groove 12 and two other smaller circumferential grooves 14 and 16. In these latter two grooves are positioned wicks MW and 16W which originate in the oil well 8 and which carry oil from the oil well to all parts of the ring. This means of transmitting oil to the spinning ring is well known and does not constitute any part of the invention. The holder, as can be seen from the drawings, comprises a circular support 18 which terminates on its interior with a circular wall 20 having upper and lower flanges 22 and 24, which flanges fit within the wide circumferential groove 12 of the ring 4. The holder thus supports the ring in a manner well understood. The holder is secured in position by tightening the screw 26 which draws the split ends of the holder together.

In the normal operation of a spinning frame, fud collects on the entire circumferential side of support 13 and along the lower exterior periphery of ring 4 as indicated at 28 in Fig. 5. Heretofore this fud could only be dislodged by scraping it away with some instrument or by using a compressed air blast. Now, however,

-I have simplified removal of the fud by providing a plurality of openings 30 which extend vertically through aeeases the support 18. These openings in the preferred form follow a circular pattern and in the aggregate constitute a major portion of the circumference. As can be seen in Figs. 2, 3, 5 and 6, the openings 30 increase in width in a downward direction as well as increasing in length as can be seen in Fig. 4. The object of this downwardly widening formation is to minimize the extent of the under surface of support 18 so that a downwardly directed air blast passing through openings 3% will dislodge the accumulated fud 28 with maximum effectiveness.

It will be understood that the openings 38 can be varied in number and dimension so long as the intermediate supports or webs 32. are adequate to carry the clamping load applied by screw 26. Instead of having long narrow slots as shown, there might be provided a multiplicity of closely spaced circular holes, for example, and other forms of openings will suggest themselves after a consideration of the present disclosure, and accordingly I do not intend that I shall be limited in any way as to the particular formation of the openings 30. The principal consideration is that the openings be of such number and shape that any fud accumulations may be blown away by a downwardly directed air blast of suflicient intensity.

The invention also applies to those spinning rings which have an exterior flange which rests on the holder as shown in Fig. 7. In this form the openings 34 will be in the flange 36 which rests on a holder 38. The fud collects at area 44) and hence will be dislodged when air is blown downward through openings 34. It will be understood that the part designated 38 could also be the ring rail, for in some installations holders are not used.

In still another form in which the flange and holder or ring rail overlap as shown in Fig. 8, aligned holes through the flange and holder or ring rail may be provided. That is, the openings 42 in the flange are aligned with openings 44 in the holder or ring rail so that fud accumulated at area 45. may be dislodged in the manner heretofore explained.

Since all textile mills have compressed air lines available throughout the plant, no special equipment needs to be installed to enable the cleaning operation to be carried out when my improved holder is in use.

When reference in the claims is made to a spinning ring holder, it will be understood that such language includes twisting rings and twisting ring holders on which fud accumulations also develop.

It is my intention to cover all changes and modifications of the examples of the invention herein chosen for purposes of the disclosure which do not constitute departures from the spirit and scope of the invention.
